This 3-way mixing and pumping unit has been designed
for small and medium central heating systems,
and can be operated manually or set automatically.
Additionally, together with an SM4 actuator they
form a compact unit. Profiled outlet holes influence
the linear characteristic of a temperature. The shaft
is sealed with a double EPDM O-ring. Because of the
outlet mixing valve with a thread flange,
commercially available pumps with a length of 130
mm and a connection thread of 1 ½” can be mounted
in this unit. Baulänge von 130 mm und einem Anschlussgewinde von 1 ½” montiert werden.
